  • This application relates to a method for updating an application program on wireless terminals in a controlled manner. Specifically, the present application is directed to a method in which updating an application program on a wireless terminal is carried out when a server permits updating the application program.
  • An application program on a wireless terminal includes executable codes and may include one or more other necessary files such as a configuration file or a property files.
  • An example of the executable codes is an application program. All these files generally reside in the wireless terminal.
  • a large mobile service provider or carrier sells communication service to millions of customers. As those customers own different makes and models of wireless terminals, it will be a big challenge to update an application program commonly utilized by all these wireless terminals. Examples of the problems are (1) how to inform these millions of customers that updating the application program is necessary, (2) how to let the customers update the application program, and (3) how to deliver the updated application program to all these wireless terminals without imposing an excessive traffic load on the wireless network. The details of these problems will be described below.
  • updating the application program may be critical and urgent, for example, because the application program contains software bugs, viruses or fraudulent codes which could cause serious security flaws or major privacy concerns.
  • a defective application program may be incapable of doing intended jobs properly on the wireless terminal. Even in such an urgent case, some customers still may not update the application program since they utilize only phone features of the wireless terminal, not affected by the defective application program.
  • a server receives an inquiry from a wireless terminal for updating an application program.
  • the server determines whether there is an updated program available for updating the application program based on information included in the inquiry from the wireless terminal.
  • the server also determines whether updating the application program of the wireless terminal which sent the inquiry is permitted or not at the time of receiving the inquiry based on the information included in the inquiry and criteria information stored in the server.

  • the router 620 is configured to sort the inquiries from multiple wireless terminals 601-1 , 601-2, 601-3 , based on some pre-defined algorithm. For example, the router 620 may sort the inquiries based on the area codes of MDN of the inquiring wireless terminal included in the inquiries. Based on such pre-defined algorithm, the router 620 may send the inquiries from a particular wireless terminal always to a specified datacenter. In the datacenter, the inquiry may be directed to any update server at the start of an updating process, and once the inquiry is directed to a specific update server, the updating process is performed by the specific update server.
  • the datacenter may include one of more download server.
  • the update server usually designates one of the download servers residing in the same datacenter as the update server by sending the DOWNLOAD_URL of the particular download server to the wireless terminal in the response to the update inquiry.
  • the update server may designate any download server residing in any of the datacenters, if necessary.
  • At least some implementations for updating the application program on the wireless terminal may involve a program, for example, for the processor of the wireless terminal and/or for the update server.
  • Program aspects of the technology may be thought of as "products” or “articles of manufacture” typically in the form of executable code and/or associated data that is carried on or embodied in a type of non-transitory computer readable medium.
  • “Storage” type media include any or all of the memory of the supporting electronics of the terminal or server that executes the respective program, such as various semiconductor memories, tape drives, disk drives and the like, which may provide storage at any time for the software programming. All or portions of the software may at times be communicated through the Internet, the wireless network serving the terminals or various other telecommunication networks.
  • Such communications may enable loading of the software from one computer or processor into another computer or processor, for example, from a host or management server into the download server or into the wireless terminal.
  • the program stored in the computer readable recording medium may be read out from the computer readable recording medium and transferred over a network, e.g., the Internet.
  • execution of the program trigger an inquiry to the update server to determine if an update is available. If no update program is available, the user need not even to be aware of the inquiry. If the update program is available, the permission determination process with respect to each particular wireless terminal provides a flexible mechanism to control or throttle actual download traffic between the wireless terminals and the download server.
  • One of the advantages of the present exemplary update technique is that at any given time, a limited number of wireless terminals can access the download server(s) and get the application program updated. Thus, however large the number of wireless terminals may be, the updating of the application program will be performed in a controlled manner, which makes the updating process manageable. As different groups (or segments) of wireless terminals will update the application program at different times, the download servers or the networks will not be overwhelmed with uncontrollable number of download requests. This improves stability and consistency of the updating system as a whole.
  • Another advantage of the present exemplary update technique is that the customers will have the flexibility to update the application program any time within a specified time window, which will result in a better user experience.
  • the above disclosed method and/or system may also establish a better control over the number of versions of a particular application program which is active in the field by utilizing the fields of the tables in the database. This will ensure better customer support and higher level of user satisfaction.
  • the method and/or system that inquire for an update of the program at each execution of the application program will not allow some version of the application program to run without updating.
  • the method and/or system disclosed herein will ensure confirmed delivery of a critical update program (e.g., patches) to all wireless terminals running the application program in a timely manner.
  • Another advantage is that an owner, a provider or a developer of the application program can know information about their application program.
  • the system processing the inquiry and update may provide various reports of patterns and trends in customer behavior, such as: on which days and at what times of the day the users prefer most to update the application program, how many versions are there in the field, etc. These pieces of information may be very helpful in developing better system design and more effective capacity-planning.
  • the exemplary update procedure may also make it possible to update only selected versions of the application program. This will be helpful when only some version(s) of the application program have issues that need to be fixed or changed.
  • the disclosed method and/or system are also helpful when only some particular batches or models of the wireless terminals need to install patches or bug-fix programs.
  • the present invention may also relate to A system for updating an application program on a plurality of wireless terminals, the system comprising:
